Not all high-end watches have to look boardroom ready. The Bell & Ross Military Ceramic Watch ($4,500) features a self-winding movement, a power reserve of 40 hours, and high-precision adjustment in four positions — all high-end features — but adds a bush-ready matte khaki ceramic case, rubber and heavy-duty synthetic fabric straps, a matte black steel buckle, and a no-nonsense black dial with photo-luminescent numerals, index, and hands.
